WINDOW SHADEAND SCREEN HOLDER.

SPECIFICATION forming part of Letters Patent No. 710,515, dated October7, 1902.

Application filed May 10, 1902. Serial No. 106,695. (No model.)

To @ZZ whom. t Wtcty concern.-

Be it known that I, JOHN ROBERTSON, a citizen of Great Britain, residingat Portland, in the county of Cumberland and State of Maine, haveinvented certain new and useful Improvements in Vindow Shade and ScreenHolders; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to improvements in rolling shade and screenholders. It is designed to secure or confine the vertical edges of theshade or screen so as to preventair or dust from entering the roombetween the shade or screen and the Window-casing.

It consists of two members, one hinged to the other midway its face, sothat the base part forms a support for the other member, whether open orclosed, and it is provided with coil-springs secured to the ends of eachmember, said spring extending transversely across the pivot-point, sothat the movable' member is locked, whether open or closed, and heldyieldingly locked in either position by said spring.

In the drawings herewith accompanying and making a part of thisapplication, Figure l is a perspective View of myimproved shade andscreen holder secured to the window-casing; and Fig. 2 is a plan View ofthe window casing and shade, the shade being shown in section, one ofthe clamping members being shown open and the other closed.

Same letters of reference referto like parts.

In said drawings, A represents a windowframe, and B a shade or screen ofthe usual roller variety.

My improved holder consists of two members, one, O, which may be calledthe base, adapted to be secured to the window-casing adjacent thevertical edge of the shade, and the other, D,which may be called theclamp, hinged to the former at a point distant from the outer edge equalto its thickness, so that when opened the base will form a seat or restfor the other member. The outer or clamping member for convenienceshould extend slightly beyond the inner edge of the base, so as toafford a convenient nger-grip for opening it, as seen at H in Fig. 2.Secured to the ends of said base and clamping-strip is a coil-,spring E,extending transversely across the pivot-line, by reason of which thespring holds the clamping member either open or closed, as shown in Fig.2. The base may be secured to the window-casing in any convenientmanner, as by screws or nails. TheY joint formed by the union of the twoparts may be sealed in any convenient manner, as by a piece of cambricF, extending across the line where the two members are hinged together,as shown in Fig. 2.

The operation of my improved shade and screen holder will be apparentfrom the drawings and description. When it is desired to adj ust theshade or screen, the clamping members are opened and the shade adjusted.The clamping members are then turned into position shown at the left ofFig. 2, firmly gripping the edges of the shade between the members ofthe holder, the springs holding them thus closed.

The advantages of my improved holder are that the two parts are distinctfrom the window-casing, can be attached to or removed from the window atwill, can be sold as an article ofl manufacture independently of thewindow-casing, andthe clamping member is automatically locked either inits open or closed position by means of the spring, which makes it muchmore convenient to operate than would be the case if the spring onlytended to hold it in its closed position, in which case it would bedifficult to hold them both open and at the same time manipulate theshade.

Having thus described my invention and its use, I claim- As a newarticle of manufacture, a window shade or screen holder consistingofabase and clamping member hinged thereto and a coil-spring secured to theends thereof and extending transversely across the pivot-line, wherebysaid spring automatically locks the clamping member both in openandclosed position.

In testimony whereof I affix my signature, in presence of two witnesses,this 8th day of May, 1902.

JOI-IN ROBERTSON.

In presence of- ELGIN C. VEREILL, NATI-IAN CLIFFORD.
